Abstract

The removal of methyl red dye from simulated wastewater using untreated, vacuum treated, and plasma treated coconut sawdust has been investigated. All treated coco lumber sawdust showed an increase in % dye removal compared to the untreated cocolumber sawdust. For each treatment, using a dye concentration of 150 mg/L, contact time of 120 minutes, adsorbent dosage of 400 g/100 mL, and ph of 7, the highest recorded % dye removal are as follows: formaldehyde treatment (20.51%), sulphuric acid treatment (40.45%), vacuum dried (61.74%), hydrogen plasma (64.54%), oxygen plasma (66.89%), and argon plasma (69.57%), compared to the untreated (11.20%). From the results of the study, it is concluded that new methods like vacuum drying and plasma treatments of coconut sawdust increase its effectiveness as an adsorbent for methyl red dye removal.
